BlitzPlus: mouse trouble

| I'm playing around with the mouse functions and for some unknown reason MouseX and MouseY refuses to work. When you click any where on the screen and hold the left mouse button the box should move with the mouse. But if MouseX and MouseY refuse to work then the box wont move. If any of you can see an error I'm missing then please point it out. here's the code I'm not sure if I'm doing something wrong or not: Include "keyboard.bb" Type Tbox Field x# Field y# Field w# Field h# End Type Type Tmouse Field x# Field y# End Type Graphics 800, 600,0,2 SetBuffer BackBuffer() mymouse.Tmouse = New Tmouse box.tbox = New tbox box\x = 100 box\y = 100 box\w = 200 box\h = 200 While Not KeyHit(K_ESC) Cls mymouse\x = MouseX mymouse\y = MouseY Text 0,0, "Hello" Text 0,10, MouseDown(1) Text 0,20, mymouse\x Text 0,30, mymouse\y If MouseDown(1) Then box\x = box\x + mymouse\x box\y = box\y + mymouse\y End If Rect box\x, box\y, box\x + box\w, box\y + box\h,0 Flip Wend End |

| Hello, For future reference, you can include the (code) and (/code) tags in your post to have your code formatted nicely. Just replace each () with a [] and it will work, like so: ;Your code here! To answer your question, keep in mind that every function which returns a value needs to have a pair of () at the end of the function. Otherwise the function will return nothing. This is why the MouseX() and MouseY () are not working. So your code should become: Include "keyboard.bb" Type Tbox Field x# Field y# Field w# Field h# End Type Type Tmouse Field x# Field y# End Type Graphics 800, 600,0,2 SetBuffer BackBuffer() mymouse.Tmouse = New Tmouse box.tbox = New tbox box\x = 100 box\y = 100 box\w = 200 box\h = 200 While Not KeyHit(K_ESC) Cls mymouse\x = MouseX() mymouse\y = MouseY() Text 0,0, "Hello" Text 0,10, MouseDown(1) Text 0,20, mymouse\x Text 0,30, mymouse\y If MouseDown(1) Then box\x = box\x + mymouse\x box\y = box\y + mymouse\y End If Rect box\x, box\y, box\x + box\w, box\y + box\h,0 Flip Wend End |

| Functions, which return a value, must be used with parentheses, e.g. MouseX(). |

| Wow, that was strange. I posted this response on the B3D forum and it ended up here somehow. I haven't programmed in BlitzPlus, so I don't know if the same fix will work. I assume it's the same. |

| First, put your code in between code tags when posting to the forum [code][/code]. It will make your code easier to read. Second, you need to put parentheses after the MouseX() and MouseY() commands. |
